Understanding Time's Nature

Time is a fundamental aspect of existence, yet its nature remains complex and mysterious. Scientists have historically viewed time as a linear progression, moving from past to present to future. However, current theories suggest that this perception may be illusory, proposing that the present, past, and future could all exist simultaneously. The discussion reveals that while physical laws imply a forward movement in time, human consciousness allows for a personal experience of time that involves reflection and anticipation.
